WINDOW-SHADE ROLLER.

Specification of Letters Patent.

Patented July 15, 1913.

Application filed July 13, 1912. Serial No. 709,175.

To all whom it may concern Be it known that we, TOM M. ANDERSON, S12,and TQM M. ANDERSON, Jr., citizens of the United States, residing atMorristown, in the county of Hamblen and State of Tennessee, haveinvented new and useful Improvements in Window-Shade Rollers, of whichthe following is a specification.

This invention relates to window shade rollers, the object in view beingto provide simple and reliable mechanism for winding the shade upon theroller and locking the mechanism against operation at any point ofadjustment of the shade.

One object of the invention is to do away with the spring usuallycontained within the body of the roller itself and substitute therefor astout and reliable spring which is associated with the roller exteriorlythereof, and combined with one of the supporting brackets, by which theroller is secured in position on the window frame.

With the above and other objects in view, the invention consists in theconstruction, combination and arrangement of parts, as will behereinafter more fully described, illustrated in the accompanyingdrawings, and pointed out in the claims hereunto appended.

In the drawings: Figure 1 is a front ele vation of a curtain shaderoller, showing the present invention applied thereto. Fig. 2 is an endview of the bracket containing the winding mechanism. Fig. 3 is alongitudinal section through said bracket. Fig. 4t is a cross sectiontaken in line with the shaft and spindle. Fig. 5 is a detaillongitudinal section through the plunger lock. Fig. 6 is a sideelevation of the combined bracket and housing with the adjacent plateremoved.

Referring to the drawings, 1 designates a window shade roller, and 2 theshade wound thereon. In carrying out the present invention, said rolleris provided at its opposite ends with spindles 3 and 4:, each of whichextends beyond the end of the roller and has a fixed relation thereto,one of said spindles 3 being mounted in an ordinary bracket 5 secured tothe window casing, while the spindle 4 at the opposite end of the rollerpasses through the adjacent side wall of a combined cylindrical housingand bracket 6 also secured fixedly to the window frame.

Within the housing 6 and fast on the end of the spindle 1- is a pinion 7which meshes with and is driven by a gear wheel 8 having a stud shaft 9which passes through a partition wall 10 within the combined. housingand bracket, and also through the outer end wall 11 thereof, said innerwall 10 being also provided with an opening to receive the spindle 4,thereby providing two points of bearing for said spindle l at oppositesides of the pinion. Between the outer wall 11 and the intermediate wallor partition 10, there is arranged a coiled spring 12, one end of whichis secured to the spindle 4:, the opposite end being secured to theinterior of the housing in which it is contained, so that said spring isutilized, when wound, to impart rotary motion to the shade roller.

Extending through the bottom of the cylindrical housing (3 is a plungerlock, embodying a small cylindrical casing 13 having openings in theopposite ends or heads lt and 15 thereof to admit of the back and forthmovements of a plunger lock 16. Within the casing, this plunger lock hasa shoulder, against which bears a spring 17 which normally holds theinner extremity of the plunger lock in engagement with the pinion so asto prevent the same from rotating. At its outer end, the plunger lock isprovided with an eye 18 adapted to receive an operating cord 19 whichextends down within convenient reach of the operator, who, by graspingand pulling said cord, may release the gear wheel and permit the springto act on the roller to wind the shade up thereupon.

In operating the shade, it is only necessary to pull down upon thereleasing cord 19, after which, by grasping the bottom edge of theshade, the latter may be either drawn down or allowed to be wound upwardby the action of the spring in the combined housing and bracket,hercinabove described. When the shade has been adjusted to the desiredpoint, the cord 19 is released, and the plunger lock thereupon engagesthe gear wheel and prevents further action of the winding spring.

l/Vhat is claimed is:

1. A curtain shade roller. a spindle projecting from one end of saidroller and having a fixed relation thereto, a spur pinion fast on saidspindle, a spur gear wheel meshing with said pinion, a roller windingcoiled spring operating on said gear wheel, a

spring pressed plunger lock for holding and releasing said pinion, and apull cord attached to said plunger lock.

2. A curtain shade roller, a spindle projecting from one end of saidroller and having a fixed relation thereto, a combined housing andbracket in which said spindle is journaled, a pinion fast on saidspindle within the housin 21- em wheel meshin 7 O b with said pinion, acoiled spring for revolving said ear wheel, a partition wall for saidhousing between the spring and gear wheels provlded W1th hearlngs forthe spindle and gear wheel shaft, a spring pressed plunger lock workingthrough the wall of the housing for holding and releasing said pinion,and a pull cord attached to the plunger look.

In testimony whereof we aflix our signatures in presence of twowitnesses.
